[0002] Gas water heater is a common household hot water preparation equipment. It uses gas as fuel, transfers heat to cold water flowing through the heat exchanger through combustion heating, so as to achieve the purpose of preparing hot water. During the use of gas water heater, the combustion of gas will produce a lot of smoke (waste gas), which needs to be discharged to the outside or public flue through the exhaust pipe to prevent the smoke from polluting the indoor air and ensure personal safety.

[0003] The flue gas discharged through the exhaust pipe has a certain amount of heat. If the flue gas is discharged directly to the outside, it will cause heat loss.

[0028] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0029] Gas water heater is a common household hot water preparation equipment. It uses gas as fuel, transfers heat to cold water flowing through the heat exchanger through combustion heating, so as to achieve the purpose of preparing hot water. During the use of gas water heater, the combustion of gas will produce a lot of smoke (waste gas), which needs to be discharged to the outside or public flue through the exhaust pipe to prevent the smoke from polluting the indoor air and ensure personal safety.

[0030] The flue gas discharged through the exhaust pipe has a certain amount of heat. If the flue gas is discharged directly to the outside, it will cause heat loss. For this reason, a condensing gas water heater has emerged. A condensing heat exchanger is set in the exhaust pipe, which can use the latent heat of the high-temperature flue gas to preheat cold water, thereby improving the heat conversion efficiency and saving at least 10% of the gas fee.

[0031] This type of condensing gas water heater has the following problems during use: the condensed water is highly acidic and corrosive to metal parts; in cold weather, if the discharged condensed water is not properly handled outdoors, the ground may freeze and cause passers-by to fall, or the drain pipe may freeze and the condensed water cannot be discharged in time, causing the unit to shut down due to water full protection, affecting normal use by users.

[0032] Based on the above problems, Figure 1 As shown, an exemplary embodiment of the present invention provides a condensate discharge device 100. The condensate discharge device 100 includes: a water collecting tank 110, a neutralization component 120 and a controller (not shown in the figure). The water collecting tank 110 is provided with a water inlet 111 connected to the condensate pipeline 101 to collect the condensate generated in the condensing wall-mounted boiler. The neutralization component 120 is used to neutralize the condensate so that the condensate forms an aqueous solution. The water collecting tank 110 is provided with a first outlet 112, and the first outlet 112 is connected to the heating system 200. The controller is configured to open the first outlet 112 when the aqueous solution meets the water replenishment condition and the water pressure in the heating system 200 is lower than the target preset value, so as to replenish water into the heating system.

[0033] The target preset value is the lowest value of the water pressure allowed in the heating system 200. In one example, the lowest value of the water pressure allowed in the heating system 200 may be 1.5 bar. That is, when the water pressure in the heating system 200 is lower than 1.5 bar, the heating system 200 needs to be replenished with water.

[0034] It should be noted that when the current water level value of the aqueous solution in the water collecting tank 110 meets the water replenishment condition, that is, the current water level value is above the lowest discharge water level line L2 and lower than the maximum safety water level line L3, and when the water pressure in the heating system 200 is lower than the target preset value, the first outlet 112 is opened to transport the aqueous solution in the water collecting tank 110 to the heating system 200, so as to replenish the heating system 200 with water.

[0035] In the present invention, the neutralization component 120 is used to neutralize the strongly acidic condensate water, and by detecting the water level in the discharge device and the water pressure in the water channel of the heating system, the neutralized condensate water is discharged into the heating system 200 through logical control, thereby achieving the technical effects of acidic water neutralization and zero discharge.

[0036] Specifically, Figure 1 As shown, the condensate discharge device 100 can be applied to a condensate wall-mounted boiler, and the condensate wall-mounted boiler is connected to a heating system 200. The condensate pipe 101 in the condensate wall-mounted boiler is connected to the condensate discharge device 100, and one of the outlets of the condensate discharge device 100 can be connected to the heating system 200.

[0037] The condensate discharge device 100 includes a water collecting tank 110, a neutralization component 120 and a controller.

[0038] The water inlet 111 of the water collecting tank 110 is connected to the condensing water pipeline 101. The condensing wall-mounted boiler will produce condensing water during the secondary heat exchange process. The condensing water pipeline 101 can be used to smoothly flow the generated condensing water into the water collecting tank 110. In other words, the water collecting tank 110 can be used as a storage box for condensing water to ensure that the generated condensing water will not overflow and cause damage to certain components of the condensing wall-mounted boiler or cause problems such as humid environment.

[0039] In actual operation, when the condensing boiler is in the secondary heat exchange process, as the heat is exchanged, the water vapor will condense into liquid condensed water. Due to gravity and pipeline pressure, the condensed water will flow along the condensed water pipeline 101 to the water inlet 111 of the water collecting tank 110 and then be collected by the water collecting tank 110.

[0040] The neutralization component 120 is disposed in the water collecting tank 110, and is used to neutralize the condensed water in the water collecting tank 110. The condensed water in the water collecting tank 110 is usually highly acidic, because during the secondary heat exchange process of the condensing wall-mounted boiler, the combustion gas (such as carbon dioxide, sulfur dioxide, etc.) will dissolve in the condensed water, making the condensed water acidic to a certain extent. If the acidic condensed water is directly discharged or used for other purposes, it may cause corrosion to equipment, pipelines, etc., affecting the service life and safety of the heating system 200 or the condensing wall-mounted boiler.

[0041] It should be noted that the neutralization component 120 can be set at any position in the water collecting tank 110. In one example, the neutralization component 120 can include a reagent kit and an alkaline neutralizer placed in the reagent kit. The reagent kit can be set at the bottom of the water collecting tank 110, or the reagent kit can also be floated in the condensed water of the water collecting tank 110.

[0042] When the reagent box is located at the bottom of the water collecting tank 110, due to the effect of gravity, the condensed water will naturally flow downward in the water collecting tank 110 and finally gather at the bottom. Placing the reagent box at the bottom can ensure that the condensed water can contact the alkaline neutralizer to the maximum extent during the flow process. Based on this, even if the condensed water flow rate in the water collecting tank 110 is small or the flow rate is slow, it can be ensured that there is enough condensed water to react with the alkaline neutralizer, thereby improving the efficiency of the neutralization reaction.

[0043] When the reagent box is floated in the condensed water, the bottom of the reagent box can lose weight and contact the condensed water. Even if there is a lot of condensed water in the water collecting tank 110, the top of the reagent box directly presses against the top wall of the water collecting tank 110, so that the side wall and bottom of the reagent box can fully contact the condensed water, thereby ensuring and improving the efficiency of the neutralization reaction.

[0044] Among them, the acidity of the condensed water after neutralization treatment is reduced, thereby forming an aqueous solution. At this time, the aqueous solution is relatively mild and no longer has strong acidity, so that it can better participate in the subsequent interaction of the heating system 200.

[0045] For example, when water replenishment is needed in the heating system 200, the water quality of the aqueous solution after neutralization treatment is relatively mild, so that the aqueous solution can better participate in the various components of the heating system 200 and be compatible with the various components of the heating system 200, avoiding equipment failures caused by water quality problems.

[0046] The water collecting tank 110 is provided with a first outlet 112, one end of the first outlet 112 is communicated with the interior of the water collecting tank 110, and the other end of the first outlet 112 is communicated with the heating system 200. Based on this, when the aqueous solution meets the water replenishment condition and the water pressure in the heating system 200 is lower than the target preset value, the first outlet 112 is opened to replenish water into the heating system 200, wherein the target preset value is the lowest value of the allowable range of the water pressure in the heating system.

[0047] In one example, the lowest value of the allowed range of water pressure in the heating system 200 may be 1.5 bar. That is, when the water pressure in the heating system 200 is lower than 1.5 bar, the heating system 200 needs to be supplemented with water.

[0048] The water pressure in the heating system 200 directly affects the normal operation of the system. If the water pressure is too high, it may cause dangers such as pipe rupture; if the water pressure is too low, it will affect the heating effect of the system.

[0049] In addition, the water level value in the water collecting tank 110 reflects the capacity of the aqueous solution in the water collecting tank 110 that can be used for water replenishment. Only when there is enough aqueous solution in the water collecting tank 110 and the heating system 200 needs water replenishment (i.e., the water pressure is lower than the normal range), the first outlet 112 will be opened to replenish water for the heating system 200. The water replenishment process has a certain influence on the stable operation of the heating system 200. By replenishing the aqueous solution in time, the water pressure temperature in the heating system 200 can be maintained, ensuring that the hot water can circulate normally in the heating system 200, so that the heating system 200 can provide a stable heating effect, and the service life of the heating system 200 can also be extended.

[0050] like Figure 1 As shown, in some embodiments, the neutralization component 120 includes a reagent kit (not shown in the figure) and an alkaline neutralizer (not shown in the figure), wherein the alkaline neutralizer is contained in the reagent kit.

[0051] The reagent box plays a role of containing and positioning in the neutralization component 120. Specifically, the reagent box can be set at the bottom of the water collecting tank 110. The reagent box can provide a special placement space for the alkaline neutralizer, so that the alkaline neutralizer can be placed in the water collecting tank 110 in an orderly manner, preventing the alkaline neutralizer from floating around in the water collecting tank 110, thereby ensuring that the neutralization reaction can be carried out in a relatively concentrated and controllable area.

[0052] When the alkaline neutralizer comes into contact with the acidic condensed water, an acid-base neutralization reaction will occur. For example, the alkaline neutralizer is sodium hydroxide, and the acidic condensed water contains hydrogen ions. The hydroxide ions in the sodium hydroxide will combine with the hydrogen ions to generate water, thereby reducing the acidity of the condensed water and eventually forming a relatively neutral aqueous solution. This neutral aqueous solution is more beneficial for subsequent interaction with the heating system 200, because various components in the heating system 200 (such as metal pipes, water pumps, etc.) have certain requirements for the pH of the water quality, and the neutral aqueous solution can reduce corrosion to these components.

[0053] When the reagent box is located at the bottom of the water collecting tank 110, due to the effect of gravity, the condensed water will naturally flow downward in the water collecting tank 110 and finally gather at the bottom. Placing the reagent box at the bottom can ensure that the condensed water can contact the alkaline neutralizer to the maximum extent during the flow process. Based on this, even if the condensed water flow rate in the water collecting tank 110 is small or the flow rate is slow, it can be ensured that there is enough condensed water to react with the alkaline neutralizer, thereby improving the efficiency of the neutralization reaction.

[0054] Each end surface of the test kit is a mesh structure, so that the side walls of the test kit will not hinder the flow of condensed water, so as to allow the condensed water to pass freely while retaining the alkaline neutralizer inside, so that the condensed water can smoothly enter the interior of the test kit and contact the alkaline neutralizer inside it.

[0055] At the same time, the mesh structure can also help increase the contact area between the condensed water and the alkaline neutralizer, because the mesh structure allows all surfaces of the alkaline neutralizer to be exposed to the condensed water, thereby increasing the rate of the neutralization reaction. For example, when the alkaline neutralizer is in a block shape, the mesh structure allows the condensed water to contact the block alkaline neutralizer from multiple directions, so that the neutralization reaction not only occurs on the surface of the block neutralizer, but also penetrates into the interior, thereby increasing the completeness of the neutralization reaction.

[0056] like Figure 2 As shown, in one example, a replenishing port 114 communicating with the inside of the reagent box can be provided on the top surface of the water collecting tank 110, and the alkaline neutralizer in the reagent box can be replenished at any time through the replenishing port 114. That is, the replenishing port 114 is located above the maximum safe water level L3 in the water collecting tank 110.

[0057] The supplement port 114 may adopt a flip-cover type sealing structure.

[0058] like Figure 1 As shown, in some embodiments, the first outlet 112 is located on the side wall of the water collecting tank 110, so that the first outlet 112 can achieve precise conduction control of the aqueous solution in the water collecting tank 110 according to the water level in the water collecting tank 110 while ensuring effective connectivity with the heating system 200.

[0059] Based on the overall structure of the water collecting tank 110, the first outlet 112 is arranged on the side wall of the water collecting tank 110, so that the first outlet 112 can cooperate with the water inlet 111 and the neutralization component 120 of the water collecting tank 110. That is, the water inlet 111 is used to introduce condensed water into the water collecting tank 110, the neutralization component 120 neutralizes the condensed water, and the first outlet 112 is responsible for transporting the treated aqueous solution to the heating system 200 under appropriate conditions.

[0060] The first outlet 112 is at a first distance from the bottom of the water collecting tank 110, and the first distance is the minimum water level L1 allowed to be discharged from the condensed water in the water collecting tank 110. If the water level in the water collecting tank 110 is lower than the minimum water level, that is, lower than the first distance, it indicates that the available aqueous solution in the water collecting tank 110 is less and insufficient to effectively replenish the heating system 200.

[0061] On the other hand, by setting the first distance, excessive emptying of the aqueous solution in the water collecting tank 110 can be avoided, so that the condensed water that subsequently enters the water collecting tank 110 cannot react with the alkaline neutralizer in time, so that the condensed water that has not reacted with the neutralization reaction is discharged. In addition, by setting the first distance, the neutralization component 120 in the water collecting tank 110 can also be effectively protected, thereby extending the service life of the entire condensed water discharge device 100.

[0062] like Figure 1 As shown, in some embodiments, a minimum discharge water level line L2 is set in the water collecting tank 110, and the minimum discharge water level line L2 is configured as the minimum water level value of the aqueous solution in the water collecting tank 110 when the first outlet 112 is allowed to open.

[0063] Among them, by setting the minimum water level value, the effectiveness and stability of the aqueous solution in the water collecting tank 110 when replenishing water to the heating system 200 can be ensured, ensuring that when the first outlet 112 is opened, there is sufficient aqueous solution and corresponding water pressure in the water collecting tank 110 to replenish the heating system 200.

[0064] The water level of the lowest discharge water level line L2 must be higher than the lowest water level L1 allowed for the discharge of condensed water.

[0065] like Figure 1 As shown, in some embodiments, the water level value of the lowest discharge water level line L2 is any value between 25% and 40% of the height value of the water collecting tank 110 in the vertical direction.

[0066] When the water level of the lowest discharge water level line L2 is lower than 25% of the height of the water collecting tank 110, the water pressure in the water collecting tank 110 may be low, so when it is necessary to replenish water to the heating system 200, the replenishment time may be too long due to the low water pressure.

[0067] In addition, a certain water level value can also ensure the continuous operation of the neutralization reaction. If it is lower than 25%, it may lead to incomplete neutralization reaction or the alkaline neutralizer being exposed to the air and becoming ineffective.

[0068] The upper limit of 40% is more considered to effectively utilize the water collecting tank 110 and the rationality of the water replenishment operation. If the first outlet 112 is allowed to open for water replenishment only when the water level exceeds 40%, it may cause excessive accumulation of aqueous solution in the water collecting tank 110.

[0069] In actual situations, one of the main functions of the water collecting tank 110 is to provide water replenishment for the heating system 200. If water replenishment is performed when the water level is too high, some opportunities for timely water replenishment may be missed. For example, if the water pressure in the heating system 200 has begun to drop, but the water collecting tank 110 is not replenished in time due to the high water level, the normal operation of the heating system 200 will be affected. Moreover, the excessively high water level may also generate additional pressure on the structure of the water collecting tank 110, affecting its service life.

[0070] It should be noted that under different environmental conditions, the water loss situation of the heating system 200 and the water inflow situation of the water collecting tank 110 will be different. The water level value of the lowest discharge water level line L2 is set to any value between 25% and 40% of the height value of the water collecting tank 110 in the vertical direction, so that the water collecting tank 110 can adapt to different operating conditions.

[0071] For example, in the cold winter, the heating system 200 may lose water quickly due to thermal expansion and contraction, etc. At this time, the lower limit of 25% of the water level of the water collecting tank 110 can ensure that there is enough aqueous solution for water replenishment while avoiding frequent excessive water replenishment, because excessive water replenishment may cause large fluctuations in the water pressure in the heating system 200. In some milder seasons or when the heating system 200 operates more stably, the upper limit of 40% can ensure that the water replenishment opportunity will not be missed due to the accumulation of aqueous solution in the water collecting tank 110.

[0072] like Figure 1 As shown, in some embodiments, a second outlet 113 is provided on the water collecting tank 110. The second outlet 113 is provided at the bottom of the water collecting tank 110 so that excess aqueous solution can be more easily discharged from the bottom of the water collecting tank 110 under the action of gravity.

[0073] The second outlet 113 can be directly connected to the outside, or the second outlet 113 can also be connected to other water collecting parts. For example, the second outlet 113 can be connected to a waste water tank, and the neutralized aqueous solution is subjected to secondary water collection and reserved for other uses.

[0074] The water pressure in the heating system 200 being within a normal range is one of the important conditions for the second outlet 113 to be allowed to be turned on. This requirement is closely related to the stable operation of the entire heating system 200.

[0075] If the water pressure of the heating system 200 is abnormal, for example, the water pressure is too high or too low, then opening the second outlet 113 may have a negative impact on the heating system 200. When the water pressure is too high, opening the second outlet 113 may cause the water in the heating system 200 to suddenly drain, causing the water pressure to drop sharply, affecting the heating effect. When the water pressure is too low, the aqueous solution in the water collecting tank 110 may need to be used first to replenish the water volume of the heating system 200, rather than being discharged through the second outlet 113. Therefore, only when the water pressure is normal, consider opening the second outlet 113 to avoid interference with the normal operation of the heating system 200.

[0076] In addition, the second outlet 113 is allowed to be opened only when the water level of the aqueous solution in the water collecting tank 110 exceeds the set water level. This is a reasonable control of the state of the condensed water inside the water collecting tank 110. When the water level of the aqueous solution exceeds the set water level, it indicates that there is too much aqueous solution in the water collecting tank 110. If the above-mentioned set water level is not set, the water collecting tank 110 will continue to store water, causing the internal water level to be too high, which will greatly increase the pressure load of the water collecting tank 110.

[0077] In this example, by setting the opening requirements of the second outlet 113, the water level value of the aqueous solution in the water collecting tank 110 can be effectively controlled to ensure that the water collecting tank 110 is in a suitable working state, while also ensuring the coordinated operation between the heating system 200 and the water collecting tank 110.

[0078] like Figure 1 As shown, an exemplary embodiment of the present invention provides a condensing wall-mounted boiler, comprising a condensate discharge device 100 as described in any of the above embodiments.

[0079] The condensate discharge device 100 includes: a water collecting tank 110 and a neutralization component 120. The water collecting tank 110 is provided with a water inlet 111 connected to the condensate pipeline 101 to collect the condensate generated in the condensing wall-mounted boiler. The neutralization component 120 is used to neutralize the condensate so that the condensate forms an aqueous solution. The water collecting tank 110 is provided with a first outlet 112, and the first outlet 112 is connected to the heating system 200. The aqueous solution is configured to conduct the first outlet 112 when the set conditions are met to replenish water in the heating system 200. The set conditions are related to the water pressure in the heating system 200 and the water level value in the water collecting tank 110.

[0080] In this example, the neutralization component 120 is used to neutralize the strongly acidic condensate water, and by detecting the water level in the discharge device and the water pressure in the water channel of the heating system 200, the neutralized condensate water is discharged into the heating system 200 through logical control, thereby achieving the technical effects of acidic water neutralization and zero discharge.

[0081] like Figure 1 As shown, in some embodiments, the condensing wall-mounted boiler further includes a circulation pump 102 , wherein the circulation pump 102 is disposed on a pipeline connecting the first outlet 112 of the condensate discharge device 100 and the heating system 200 .

[0082] In this example, when the aqueous solution meets the set conditions, the first outlet 112 is opened, and the aqueous solution in the water collecting tank 110 is transported to the heating system 200 under the action of the circulation pump 102 to replenish the heating system 200 with water.

[0083] like Figure 3 As shown, an exemplary embodiment of the present invention provides a condensed water control method, which is applied to a condensing wall-mounted boiler as in any of the above embodiments, and the control method comprises the following steps: Step S100: Determine whether the current water level value of the aqueous solution in the water collecting tank in the condensate discharge device meets the water replenishment condition.

[0084] Step S200: Determine whether the water pressure of the heating system connected to the condensing wall-mounted boiler is lower than a target preset value, wherein the target preset value is the lowest value of the allowable range of the water pressure in the heating system.

[0085] Step S300: When the aqueous solution meets the water replenishment condition and the water pressure in the heating system is lower than the target preset value, the aqueous solution in the water collecting tank is replenished into the heating system.

[0086] In step S100, when the current water level of the aqueous solution in the water collecting tank 110 is above the lowest discharge water level line L2 and below the maximum safety water level line L3, it is determined that the aqueous solution meets the water replenishment condition.

[0087] In step S200, the water pressure in the water channel of the heating system 200 needs to be maintained within a reasonable pressure range during operation. When the water pressure in the heating system 200 is lower than the minimum value of the allowed range, it indicates that water needs to be replenished in the heating system 200.

[0088] In one example, the lowest value of the allowed range of water pressure in the heating system 200 may be 1.5 bar. That is, when the water pressure in the heating system 200 is lower than 1.5 bar, the heating system 200 needs to be supplemented with water.

[0089] In step S300, when it is determined that the aqueous solution meets the water replenishment conditions and the water pressure in the heating system 200 is lower than the target preset value, the first outlet 112 is controlled to be turned on, and under the driving action of the circulating pump 102, the aqueous solution in the water collecting tank 110 is replenished into the heating system 200.

[0090] In this example, whether the current water level of the aqueous solution in the water collecting tank 110 reaches the lowest discharge water level line L2 is used as a prerequisite for replenishing water to the heating system 200. The heating system 200 has a built-in water pressure detection function. When the water pressure in the heating system 200 is lower than the target preset value, i.e., 1.5 bar, and the above-mentioned water replenishment conditions are met at the same time, the condensate discharge device 100 will start the circulation pump 102 to replenish water to the heating system 200.

[0091] When the water pressure in the heating system 200 is greater than 1.5 bar, the circulation pump 102 is controlled to stop and the first outlet 112 is closed.

[0092] like Figure 3 As shown, in some embodiments, the condensed water control method further includes the following process: In the process of replenishing the aqueous solution in the water collecting tank 110 into the heating system 200 , a first real-time water level value of the aqueous solution in the water collecting tank 110 is detected.

[0093] If the first real-time water level value is lower than the lowest discharge water level line L2, it indicates that the water level of the aqueous solution in the water collecting tank 110 is low. At this time, the aqueous solution does not meet the water replenishment condition. The circulation pump 102 is controlled to stop and the first outlet 112 is closed.

[0094] In addition, when the water pressure in the heating system 200 is lower than 1.5 bar, and the first real-time water level value of the aqueous solution in the water collecting tank 110 is lower than the minimum water level value L1 allowed by the condensed water in the water collecting tank, the circulating pump 102 should also be closed and water replenishment should be stopped to avoid dry pumping of the circulating pump 102.

[0095] like Figure 3 As shown, in some embodiments, the condensed water control method further includes the following process: When the aqueous solution in the water collecting tank 110 meets the water replenishment condition and the water pressure in the heating system 200 is greater than or equal to the target preset value, it indicates that the heating system 200 does not need water replenishment at this time. In order to avoid the water level of the aqueous solution in the water collecting tank 110 being too high and causing load impact on the water collecting tank 110, the second real-time water level value of the aqueous solution in the water collecting tank 110 is detected at this time.

[0096] If the second real-time water level value is equal to or higher than the maximum safe water level line L3 of the aqueous solution in the water collecting tank 110 , the second outlet 113 at the bottom of the water collecting tank 110 is controlled to be turned on to discharge the aqueous solution to the outside through the second outlet 113 .
